Tag image

Tag image can return content tags for thousands of recognizable objects, living beings, scenery, and actions that appear in images. Tags are not organized as a taxonomy and do not have inheritance hierarchies. Tagging is not limited to the main subject, such as a person in the foreground, but also includes the setting (indoor or outdoor), furniture, tools, plants, animals, accessories, gadgets, and so on.
